Question

Before mitosis begins, a cell makes a copy of the DNA in the nucleus. What term is used to describe this process of making an exact copy of the DNA?

Answer 1

DNA replication, I do believe. 

Answer 2

Replication

Step-by-step explanation:

The process through DNA makes an exact copy of itself is known as replication. During reproduction organism passes its genetic information to its young ones by replicating and transferring the DNA. During replication, the double helix unwinds and the base pair separate. On the parent strand, enzymes move and read the bases and thereby produce a copy of it.

The strands of DNA re-twist and produce two daughter molecules.
